Specification forming part of Letters Patent N 0. 185,240, datedDecember 12, 1876 application filed September 16, 1876.

To all whom it may concern Be it known that I, FRANCIS E. KERNO- CHAN,of Pittsfield, in the county of Berkshire and State of Massachusetts,have invented a new and useful Improvement in Compound Valve for Wash-Basins, Bath- Tubs, Water-Closet Basins, &c.,of which the following isa specification:

Figure 1 is a front view of a wash-basin to which my improvement hasbeen applied. Fig. 2 is a vertical section of the same, taken throughthe line 00 m, Fig. 1, and looking in the direction of the arrow.

Similar letters of reference indicate corresponding parts.

The object of this invention is to prevent sewer-gas fromescapingintothe housethrough the discharge-pipes of wash-basins,bath-tubs, water-closet basins, 86C.

The invention consists in the combination of two'or more valves,provided with a single "alve-stem, with the inlet and discharge-pipes ofwash-basins, bath-tubs, water-closet basins, 8220., and in thecombination of the crank, the connecting-rod, and the sliding rod withthe single stem of the two or more valves, as hereinai'ter fullydescribed.

A represents a wash-basin. B and C are the warm-water and cold-waterinlet-pipes.

D is the discharge-pipe. E is the overflowpipe, which enters the upperend of the discharge-pipe D. In each of the pipes B I) C is placed astop cook or valve, F. The three valves 'F are arranged in line witheach other, and are all attached to the same stem G, so that they mayall be opened and closed at the same time and by the same operation.

The three valves F should all rest upon and be attached to a bar, H, sothat they cannot be moved out of line with each other by the bending ofthe pipes B D C.

The shells of the valves F may be made solid, with or without the bar H,if desired.

The valvestem G may be operated in various ways to open and close thevalves F. I will describe a simple and convenient way of doing this, butdo not wish to be limited to that arrangement.

To one end of the valvestem G is attached a short crank, I, to which ispivoted the lower end of a connecting-rod, J. The upper end of to it andto some suitable support, to increase the friction.

When the valves F are open Water may be admitted to the basin byoperating the faucets K, and may be discharged the same as if no valvesF were used.

When the valves F are closed no water can be admitted into the basin,and no sewer-gas can escape from the discharge'pipe into the room, sothat there can be no overflowing on account of the closing of the valvein drainpipe.

In the case of bath-tubs the same arrangement is used.

In the case of water-closet basins only two valves will be used, as saidbasin is never supplied with a warm-water pipe.

In the case of water-closet basins-the inletpipe should be carried abovethe basin, and then brought down to it, so that the downwardly-extendingpart of said pipe may contain enough water to flow out after the valveshave been closed for the after-wash, and to furnish the usualwater-seal.

Having thus described my invention, I claim as new, and desire to secureby Letters Patent 1. The combination of two or more valves, fastenedside by side upon a common support and operated by a single shaft, stem,or lever, the latter being made to pass through all the valves and openor close all of them at once by apart or whole revolution, and beingactuated by attachments, substantially as herein shown and described.

2. The combination of the crank I, the connecting-rod J, and the slidingrod K with the stem G of the valves F, substantially as herein shown anddescribed.

FRANCIS E. KERNOCHAN.
